This invention relates to woodworking machines and more particularly to a combination Woodworking machine having means for 4supporting a plurality of woodworking tools @and selectively bringing the same into operative position.

An important object of the invention is to provide a structure of this character such that only one tool is in operation at a time and the transfer of power to the operated tool is made simple and is readily accomplished.

A further obj ect of the invention is to provide a structure of this character wherein j there is a rotatable support for the various tool elements and means for rotating this support to bring any of the tools into operative position, each tool having a driving pulley which, when the tool is in operative position, aligns with an idle pulley alterlgaf) nately receiving the drive and capable of .transferring the drive belt to the pulley of fthe operated tool upon actuation of a shifter controlling the position of the drive belt.

A further object of the invention is to pro- 25 Vide a construction of this character, wherein the drive coacts with the rotatable element and with a stop to maintain the rotatable element with the desired tool in working position.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a plan view partially broken away of a woodworking machine constructed in accordance with my invention;

Figure 2 is a longitudinal sectional view on the line 2 2 of Figure 1;

Figure 3 is a transverse sectional view therethroug'h Figure 4 is a section on the line 4-4 of Figure 1.

Referring now more particularly to the drawings, the numeral 10 generally designates a base of any suitable character having arising therefrom a pair of standards or side members 11. Pivoted to the side members at one side edge thereof is a table top 12, which is adjustable about its hinged connection by a lever actuated cam bar 13 supported from the side members adjacent the opposite side edge thereof and engaging the face of the table. The table 12 has in alignment with the approximate center of the side members 11 and adjacent the side edges thereof openings 14 and 15.

Rotate-bly mounted in the side members 11 is a shaft l'havi-ng secured thereto a tool carrier which comprises spaced spiders 17, each of which has at a plurality of points bearings 18. The bearings of the spiders align to receive transversely extending shafts 19, each having secured thereto at one end 'thereof -a tool or member to be operated, generally indicated at`20, and at the lopposite end thereof a. drive pulley 21. rIhel members to be operated preferably include saws 22 of different types, such as rip, lcross-cut and rabbeting saws, a yplaner head 23, a molding head 70 24 anda p'ulley25. Any combination desired may be employed. One endof the shaft 16 projects through the lside member 11 and is provided with a handle 26 by means of which the shaft .may be rotated to bring any of the elements to be driven into alignment with the opening 15 of the table to cause the same to project therethrough. At the same time, the pulley 21 of the shaft upon which the member to be driven is mounted will align with the opening 14 of 'the table, so that the action of the drive belt may be observed.

A cross bar27 arranged between and connected to the side members 11, is located slightly above and laterally beyond the highest or that pair of bearings 18 of the tool in position for use. Rabbet pawls 28 pivoted to the cross bar 27 extend from the bar in the direction yof the highest pair of bearings 18, and vhave their inner or free ends engaged with such bearings. The pawls 28 hold the tool carrier against rotation in the general direction of rotation of the tool in position for use, and permit the free manual rotation of the tool carrier in the opposite direction to permit lanother tool to be arranged in position for use. During' the adjustment of the tool carrier, the pawls 28, which extend across thev paths of motion of the bearings 18, are prevented from falling into inoperative po- 100 sition by the bearings, and automatically engage the bearings of the tool being adjusted into position for use immediately on the arrangement of the tool in such position. Mounted upon one of the side members is an idler pulley 29 which, When the bearings of a given shaft are engaged With the rabbet pavvls, aligns With the pulley 2l of this shaft. A driven belt 30 controlled by a shifter 31 is provided, this belt extending in such direction that the strain applied thereto, When the same is engaged with the pulley 2l of a given shaft, tends to rotate the structure in a direction forcing the bearings ofthe shaft against the paWls 28. Through the shifter, this belt may be positioned either upon the idler pulley or upon the pulley 21 of a shaft aligned therewith. y

From the foregoing, it Will be obvious that in order to bring a selected element into play, it is merely necessary to shift the belt to the idler pulley, rotate the structure until the desired driven element is aligned with the opening 15 of the table and projects therethrough, regulate the table so that the element has the desired projection and then by manipulation of the shifter to force the belt upon the pulley 2l of the shaft of the element. The element is then driven and may be employed. By following this procedure, a series of operations upon a piece of material may be performed in succession Without the necessity of transferring the material to different machines. The pulley 25 is preferably employed to enable a povver take-off for use with a band saw, mortise and tenoning machine or other implement. Such implements may be supported from the table, if desired.

Since the construction hereinbefore set forth is capable of a certain range of change and modification Withoutmaterially departing from the spirit of the invention, VI do not limit myself to such specific structure except as hereinafter claimed.

I claim In a Woodworking machine, a rotatable carrier having circumferentially spaced pairs of bearings and a shaft mounted in each pair of bearings, tools fixed to corresponding ends of the shafts, pulleys upon the outer ends of .the shafts, an idler pulley With Which the pulley of the highest or selected tool alines, a cross bar arranged slightly above and laterally beyond the carrier, rabbet paivls pivoted to the cross bar and extending therefrom across the paths of motion of the bearings and having their free ends arranged in engagement With the highest bearings, said pa-Wls holding the carrier against movement in the general direction of rotation of the tool in position for use and adapted to permit the free manual rotation of the carrier in the opposite direction, said pavvls being prevented by the bearings from moving into inoperative position D o during the adjustment of the carrier so as to effect their automatic engagement with the bearings of the tool moved into position for use, and a drive belt selectively positionable upon said idler pulley or upon the pulley of the tool in position for use.

In testimony whereof I hereunto aliix my signature.
